Yes, it is very important otherwise some teachers may count the problem wrong.
Answer:
A) 29
Step-by-step explanation:
DG = GJ
GJ = DG = 4x + 17
DJ = DG + GJ
11x + 25 = 4x + 17 + 4x + 17
11x + 25 = 4x + 4x + 17 + 17 {Combine like terms}
11x + 25 = 8x + 34
Subtract 25 from both sides
11x = 8x + 34 - 25
11x = 8x + 9
Subtract 8x from both sides
11x - 8x = 9
3x = 9
Divide both sides by 3
x = 9/3
x = 3
DG = 4x + 17
= 4*3 + 17
= 12 + 17
DG = 29
Those tiny bars crossing those segments mean they are congruent
therefore you have isosceles triangles there
angles opposing congruent sides in isosceles triangles are also congruent
so
the other 2 angles in the 24 degrees triangle are (180-24)/2=78 degrees
now the angle close to the 24 from the 44 degrees triangle is also 78, that means that the third angle in the 44 triangle is 180-44-78=58
also the angle close to y is 58 (because of isosceles)
therefore y = 180-58=122 degrees
Look at the attachment
The line bisects the cord which we have to find
- Length of chord=12cm
- Half of the cord=12/2=6cm
- Radius=10cm
Its a right angle triangle
- using Pythagorean theorem






Distance of the chord from centre is 8cm.
